ADJUSTABLE wEATH Erz-STRIP.

SPECIFICATION forming part of Letters Patent No. 343,429, dated June 8, 1886.

Application filed March 29, 1886. Serial No. 196,962. (No model.)

To @ZZ whom it may concern:

Be it known that I, KIRK S. BLANCHARD, a citizen of the United States, residing at Clarendon, in thecounty of Orleans and State of New York, have invented certain new and useful Improvements in Adjustable Weather- Strips; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Figure l is a front view of the lower portion 'of a door provided with luy-improvement, showing parts broken away. Fig. 2 is a horizontal sectional view on line x x, Fig. 1, looking upward. Fig. 3 is a vertical sectional view of a slight modification of the device. Fig. 4 is a vertical cross-sectionvof the same. Fig. 5 is a front view of a door with portions broken away, showing the device applied to the side edge of a door; and

d Fig. 6 is a perspective detail view of the casting for holding the end of the spring.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of weather-strips in which a strip is held within a longitudinal groove or recess in the lower edge of the door orA in a casing along the lower edge or side edge of the door, and in which the stripmay be forced out of the groove or casing when the door is closed; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the bottom rail of the door-frame. B B are the janibs, and O is the door. The lower edge of the door is formed with a longitudinal groove or recess, D, extending from the hinge-edge of the door to the latch-edge, and a strip, E, of wood, rubber, or wood having a rubber stri p in its lower edge, fits within this groove or recess, sliding up and down within the same. An elbow-lever, F, is pivoted at its bend between two lips, G G, projecting from a block or plate, H, which is secured in the bottoni of the groove or recess by bore, bearing with its inner end against the upwardly-projecting arm J of the elbow-lever, and projecting beyond the edge of the door with its outer end. A screw, M, having aY large Hat head, is secured in the door-jamb, for the purpose of forming an abutment for the projecting end of this bolt. The inwardlyprojecting arm N of the elbow-lever is pivoted to a short bar, O, which slides in a vertical groove, P, in the side of j the longi. tudinal groove, and the lower end of this bar has a projecting stud, Q, by which the strip is pivoted to the bar, the stud passing through the strip near its upper edge. The bar has still another stud, R, against which the inner free endof a spring, S, bears, serving to raise the strip, and the outer end of this spring is secured in a casting, T, near the latch-edge of the door in the groove in the lower edge of the door. This casting is formed with a groove in one side, the spring fitting in the said groove U, and the end of the spring is drawn down through a perforation, V, in the casting, extending from the groove and secured by being bent at the under side of the casting, the groove being in the upper side of the casting. The casting is secured to the bottom of the longitudinal groove by means of a screw, WV, which passes through the block in .a perforation, X, parallel with and connecting with the perforation for the end of the spring, so that the screw will hold the end of the spring.

If the door is too thin to admit of a groove being cut in its lower edge, the device is placed upon the outer side of the door, as shown in Figs. 3 and 4, and covered by means of a casing, Y, which is secured to the face of the door and held outfrorn the face of the door by means of studs Z, projecting between the outer side of the casing and the face of .the door.

The operative parts of the device are the same as in the formerly-described form.

IOO

In Fig. 5 is shown a modication of the dethis forni the strip is pivoted at its middle to a short bar, Af, which is pivoted to thc lower end of a lever, l', pivoted. at its middle upon a stud, C', in the `groove, and the upper end of this lever is foriined with a perforation, through which passes the reduced inner end, D', of a bolt, E', which projects outside of the edge of the door, and slides in a perforation in the saine, and a spring, F', is coiled around the inner reduced end of the `bolt and bears against the inner end of the bore, and the inner side of the upper end ofthe lever, forcing it and the bolt out. lt will now be seen that when the door is closed the boltis pushed in' ward on coming in contact with the flat-headed screw in the jamb, and the bolt will tilt the level', so that the linner end of the lever will force the strip outward, causing it to bear against the sill or janib ofthe frame, and thus preventing draft or dampness from entering between the edges of the door and the frame. Vhen the door is opened,the spring will bear against thc lever and raise the strip, drawing it into the groove or casi ng.

i The entire device may easily be applied to any door by simply either makingthc groove and its recess and bore in the edge of the door, if the dooris sufficiently thick toad mit of their being made, or if thcdooris not of a suflieient thickness the easing may be secured to the face of the door together with the paris of thc device which must be inserted in the groove if the door is of sufficient thickness to have the groove formed in its edge.

The lower edge of the strip may either be plain, if the strip is made either entirely,T of wood or metal or entirely of rubber, or it may be made with a strip of rubber inserted into the lower edge of the pivoted strip.

The strip being pivoted at its middle will be able to roel; uponiis pivot, so thatit may bear against thcsill or jamb, if the said sill or jainb is not parallel with the edge of the door, and the strip may likewise yield to any unevenness in the sill or jainb.

I am aware that heretofore doors have been provided with autornaticallvadj ustable wrath' er-strips,whieh, with their actuating lneehanism, are housed in a groove in the bottom of a door, said mechanism consisting ol' an elbowlever connected to the strip and to a rod protruding beyond the edge of the door, a sp1-ing being used to retract said strip; and I do not claim such construction, broadly; but

l1 claim and desire to secure by Letters Patcnt of the United Statesl.. The combination of a door having a longitut'linalgroove in its lower edge, formed with an upwardly-cxtending recess and with a vertical groove at the middle of one sidc,and having a horizontal bore extending from thchingeedge to the upwardly-extending reccss,astrip extending the entire length of the groove and sliding in the saine, a flat bar sliding in the vertical groove and having three studs upon its face, the lower one of which is inserted into the strip at its middle, a plate secured in the bottom of the groove of the door and having two perforated ears, an elbow-lever pivoted upon a pin between said cars and having its inner end pivoted to the upper stud ofthe ilat bar, and having' its upper arm projecting in the recess of the groove, a bolt sliding in the horizontal bore in the door and bearing with its inner cnd against the upwardly-projecting arm of the elbow-lever, and a spring bearing against the under side of the central stud of the flat bar with its free end and secured in a casting in the bottoni of the groove near the latch end of thc saine, as and for the purpose shown and set forth.

2. rlhe combination of the casting having the groove in one face and two pcrforations connecting with each other and extending through tl1eeasting,with the spring having its inner portion resting in the groove and having its end bentandinserted through the per i'oration and bent at the other side, and the screw passing through thcpcrforation bearing against the bent end of the spring, as and for the purpose shown and set forth.

In testimony whereo l' affix my signature in presence of two witnesses.
